The development of digital platforms and social media has profoundly transformed the way in which the public accesses health-related information. In this context, algorithmic recommendation systems play a decisive role in the selection, prioritisation and dissemination of health content. This article analyses how these systems may facilitate the spread of health misinformation and affect media pluralism in Spain during the period 2020–2025. Based on a conceptual and regulatory review, it examines the tensions between algorithmic transparency, freedom of expression and the protection of public health. It also analyses how these dynamics fit within the Spanish and European legal frameworks, paying particular attention to new digital regulations. Finally, it proposes criteria for transparency, auditing and institutional cooperation aimed at reducing the risks associated with health misinformation in digital environments.
